' VALVE-CONTROLLING MECHANISM.

Application filed. February 23, 1916. Serial No. 80,034.

To all'whomitmwy concern: Y

Be it known that Lllnivnr H. MERCER, a Claremont, in the county of Sullivan and State of New Hampshire, have invented certain new and useful Improvements in Valve- Controlling Mechanism, of which the following is afull, clear, and exact specifica-- tion.

My invention relates to valve controlling mechanism. I

It has for its object to enable an operator to control a valve inan improved'manner. More specifically, my invention has for its object to provide improved means whereby an operator may adjust a plurality of tively distant point. specific object of my invention is to provide improved adjustable means whereby an operator of a channeling machine, when located at any one of a plurality of distant points, may control any one ormore of a plurality of exhaust controlling valves or sets of exhaust controllingvalves, such as the upperund lower exhaust controlling valves for the piston cylinders,

and thereby with reater facility regulat the cushioning e ect of the exhaust at piston travel.

In the accompanying drawings, I have,

for purpose of illustration, illustrated one embodiment which my invention may as sume in practice, the same being shown as applied to use in connection with a well known "form of duplex it is not limited to use in In these drawings,-

that connection.

:Inth'e illustrative construction disclosed exhaust channeler of the general type described and claimed in the Mercer and Champagne atent No. 1,131,256, granted March 9, 1915, comprising atruck 1 mounted upon wheels 2 and movable along a't'rack 3, this truck 1 carrying a motor, frame 4; in which crossheads 5, carrying channeler gangs 6, are

' mounted and movable, preferably 'u an out of step relation, by pistons? moving in cylinders 8, allin a well known manner. As usual, the motoii frame l is mounted upon a horizontally disposed trunnion shaft or bar 9 carried by the truck 1, and is adjustable longitudinally of the member 9, so that j truck 1,:aslshown, or be adjusted to a position at the opposite end suitable part of the truck, being removed and re-at'tached to the unoccupied portion of the member 9, or truck. As the construction and operation of suchduplex chan-- nelers is well known, it is unnecessary to 8 is a detail view-of a part of the' the lever mechanism behave shown a duplex upper and lower exhaust the present purposes to go more into detail in describing the operation thereof than to say that as air or steam is admitted to the cylinders 8 of the chopping engine through ports 11 and 12, under the control of suitable valve mechanisms 13 operatively connected to the crossheads 5, and also under the control of the combination or distributing valve 14, the pistons 7 and gangs 6 are alternately operated, and the exhaust normally passes out of the cylinders through ports 15 and 16 which are controlled by suitable upper and lower exhaust controlling valves 17and 18, respectively.

In my improved construction, I have provided improved means whereby an operator posted at one side of the machine, as for instance when seated 011 trol either one or both controlling valves 18,

of the lower exhaust so that as the work varies the desired cushioning effect may be maintained beneath the pistons'7, z'. e. between the same and the lower ends of the cylinders. These means, in the embodiment of my invention herein illustrated, include a plurality of cranks 19 and 20 fixedby nuts 21 to the threaded rear ends of the elongated stems 22 on the valves 18, and rotatable with those stems, the latter being extended rearwardly through spools 23 (Fig. 2) a sufligcient distance to permit the cranks and their hereinafter described, to clear connections,

the back of the machine.

all obstructions on s shown in Fig.

vided to hold these cranks in each position of adjustment, an integral sleeve 24 being provided on the rear end of each of these spools 23, and having clamped thereto an outer split, sleeve-like member 25 in which is seated a plurality of plungers 26 having 1 coiled springs 27 seated therein and acting tatable with each between the plungers and a shoulder portion 28 on the sleeve 25, in such a manner as normally to project the plungers outward into suitable, radially arranged notches '29 formed in a flange-like member 30 there being one of these chambers fixed to and roof the cranks 19 and 20.

hen the several parts are in the position illustrated in Figs. 1, 2, 3, and 4, the crank 19 extends laterally to the right and slightly upward, while the crank 20 extends laterally to the left and slightly downward. As shown, the crank 19 is also pivotally connected by a suitable washer and pin con- 32, and this link is in turn adj ustably-connected through a slidable setscrew connection 33 with a cooperating member 34 pivoted at 35 to a substantially 7 parallel crank 36 rotatable with a tubular the seat 10, may con-,

The crank 20, on the the valves 18 are operable from the operators seat 10 by turning the front end or ends of either or both of the members 37-46. In order to enable these members to be so turned, a handle member 47 is fixed to the front end of the member 37, and a second handle member 48 is pivoted at 49 to the front end of the shaft 46, the arrangement being such thatthe handle 48 may be rotated and moved in a plane atright angles to its plane of rotation toward or from the handle 47, which has only a rotary .movement, so that an operator may rotate either handle when desired, or grasp both and thereupon adjust both valves 18 simultaneously,a tooth 50 preferably being provided on one of the members which is engagable with a serrated surface 51 on the other, to facilitate the turning movement, and a hook 52 preferably being provided on one of the members and engageable over a shoulder 53 on the other, to hold the members together when desired.

In my improved construction I have also providedimproved means whereby either or both ofthe the operator when heis at either side of the machine as, for example, when the seat 10 is in either of its two positions as a result of the standard 4 being adjusted longitudinally along the trunnion bar 9. however, these" meansalso enable the device to be operated when the operator is standing in thereof- These means includehandle oper-' ated mechanism similar scribed but located on the opposite side of the machine and connected I tached through a setscrew58 to a longer 'member 37 which is ournaled in an outer transversely extending link 59, and this link is in turn pivotally connected at its opposite.

end to a crank 60 extending in an opposite direction from the crank 56 and fixed to a front of the machineor at either side to the valves 18 through supplementary connections. As shown, the crank 20 is, for this purpose, piva short, laterally valves 18 may be adjusted by V Obviously,

He -may also independently adjust 62, it beingunderstood that, as in the case the lever 48 and thereby vary the cushionof the connections between these operating ing effect of the fluid in the lower end of the handles and the cranks 56 and 60, this mechopposite cylinder by controlling the exhaust anism is in all vrespects a duplicate of thethereof, Furthermore, if he'so desires, he 7 5 mechanism herein above described in detail may, by grasping the two handles 47 and as carried on the opposite side of the ma- 48, turn them both and thereby adjust both chine. i of the lower exhaust controlling valves 18, Cotiperating with the means for controlthe tooth 5O on the, member 48 then engagling the lower exhaust controlling valves 18, ing the serrated face 51 on the member 47 just described, I have also provided means and acting to move that member with the for controlling the upper exhaust controlmember 48. When the operator so desires, ling valves 17 whereby these valves may be he may also, by manipulationof the clip 52, adjusted relative to one another and simullockthe two members together so that they taneously operated, and whereby an open will move as one and remain connected. It ator while in substantially the same powill of .course be obvious that when the sition may adjust both these valves and motor frame 4 is adjusted to the opposite the lower exhaust controlling valves. As end of the trunnion bar 9, and the seat 10 shown, these means are connected to elontransposed, the operator. will be able simigated threaded stems '63 on the valves 17, larly to control the position of the lower which extend outward at the rear of the exhaust controlling valves 18 from that machine, through threaded sleeved memlocation. So far as the operation of the bers 64, and include upstanding substanupper exhaust controlling valves '17 is contially parallel cranks 65 and 66, preferably cerned, it will'be noted that these'likewise formed of spring steel, and fixed by; nuts may also be operated when the operator is 67 to the outer ends of these stems in such at either side of the machine, by simply opa manner that the valves turn with the crating the handles 80 and 81 of the rod 79, cranks.
